Helen Helliwell, CEO of the Invictus Games in Birmingham, hopes that Prince Harry and other members of the royal family attend the event when it returns to the U.K. in 2027.

Almost as importantly, the estate is Princess Diana's final resting place. She was buried in the grounds of the residence at her brother’s request. Her grave is located on a small island nicknamed "The Oval," in the center of an artificial lake on the estate. Her burial place is not accessible to guests or any member of the public.

As the 2027 Invictus Games in Birmingham draw closer, speculation about whether members of the Royal Family will attend continues. While Prince Harry has expressed hope that his family will support the event, a former royal butler remains skeptical about Prince William’s potential attendance.
